M. Abd El-Fatah | I. El-Wardany | E. Abdallah | Marwa Sh.
This study was conducted to investigate the effect of in ovo injection of broiler eggs with different levels and forms of selenium on growth performance and some blood parameters of post hatched chicks. A total of 300 fertilized eggs obtained from a commercial Arbor Acres broiler breeder flock, were used in the present experiment. They were divided randomly into six treatment groups, 50 eggs each. The first one was kept as a control– non injected group, the second group (sham) injected with phosphate buffered saline (PBS), the 3rd and 4th groups were injected with selenium nanoparticles (SeNPs) at 10 and 20 ug/egg, while the 5th and 6th groups were injected with organic selenium (Se-Methionine) at 50 and 100 ug/egg , respectively. All eggs were incubated in a forced draught incubator at the recommended temperature, relative humidity and turning patterns .The in ovo injection procedure was done at the 16th day of incubation. The criteria of response includes: live body weight, weight gain, feed consumption, feed conversion ratio, total protein, albumin, globulin, A/G ratio, cholesterol, triglyceride, HDL and glucose. The results showed that the supplementation of Se did not significantly affect growth performance traits. Supplementation of nano-Se increased plasma concentrations of total protein, albumin and HDL, and decrease glucose, however, no significant differences in globulin, A/G ratio, cholesterol and triglyceride levels. It can be concluded that the use of 20 ug /egg of Nano-Se caused an improvement of growth performance and feed conversion ratio without negative effects on blood constituents.

2018
A. Metwally | M. Ragab | S. El-Miniawy | S. Youssef
Due to the expansion of strawberry nursery cultivation, transplant production has become an important industry in Egypt. Nitrogen and phosphorus are the most important nutrients affecting the number and quality of strawberry transplants. However, no empirical research exists addressing the optimal requirements of nitrogen and phosphorus fertilization rates for strawberry nurseries in Egypt, until now. This study was conducted at a private farm in Abo Ghalib, Giza Governorate, Egypt during the two successive summer seasons of 2015 and 2016 to determine the optimal requirements of nitrogen and phosphorus fertilizations for Festival strawberry cultivar nurseries via evaluating the influence of four nitrogen rates (83, 100, 117 or 134 kg N/feddan) and five phosphorus rates (38, 62, 74, 86 or 98 kg P2O5/feddan) in a factorial experiment. Results revealed that increasing the rates of nitrogen and phosphorus fertilizations increased the number of main runners/mother plant and number of marketable transplants/m2, and enhanced all vegetative growth parameters, leaf SPAD readings, leaf relative water content, crown diameter, crown carbohydrates, and leaf mineral content in both growing seasons. On the contrary, both elements had an inverse effect on leaf total soluble phenols. Thus, the study recommends to the nurserymen of Festival straw-berry cultivar to apply 117 or 134 kg N with 98 kg P2O5 per feddan under pure sandy soil condition which gave the highest number of transplants with high quality and subsequent high quality crop in the field.

Y. ElAbdkrem | R. Abdrabou | M. El-temsah | M. Abd El-hady
Two field experiments were carried out at a private farm (newly reclaimed soil) at Somusta city, Bani-Suif governorate, Egypt, during 2014 and 2015 growing seasons. These experiments aimed to evaluate the application of different nitrogen sources and their combinations for increasing the productivity and quality of yellow maize (zea mays). Results showed that: Maize plants fertilized with120 kg MN/fad. recorded the greatest leaves number/plant (12.67) and number of green leaves /plant (12.67) after 45 days from sowing, however, the applied application of 60 kg MN/fad + 60 kg ONP /fad gave the maximum number of leaves /plant (15.17 and 17.83) and number of green leaves /plant (15.17 and 16.33) at stages of vegetative growth after 60 and 75 days from sowing, respectively. application of 60 kg MN/fad + 60 kg ONP /fad gave the highest values of leaf area index (LAI) at all stages of vegetative growth 3.16, 3.98 and 6.39 from 45, 60 and 75 days from sowing, respectively. At harvest maize plants fertilized with 60 kg MN/ fad + 60 kg ONP /fad recorded the highest value of grains number/row (32.83) followed by 60 kg MN/fad + 60 kg ONC/fad. the highest values of ears number/plant were recorded with the treatments 60 kg MN/ fad + 60 kg ONC /fad, 60 kg MN/fad + 60 kg ONP/fad and 60 kg MN/fad + 60 kg ONF/ fad with the same value (2.00). Data also revealed that the highest value of grain weight/plant (274.49) was recorded at 60 kg MN/fad + 60 kg ONP/fad treatment. Application of 60 kg MN/fad + 60 kg ONP/fad produced significant maximum grain yield (3.05 ton/fad.), biological yield (6.37 ton/fad) and grain crude protein yield (296.83 kg/fad). Maize plants treated with 60 kg MN/fad + 60 kg ONP/fad gave the highest values of grain and straw nitrogen percentage by 1.17 and 0.42% respectively. In addition the highest values of grain and straw phosphor percentage (0.49 and 0.20 %) and potassium percentage (4.30 and 1.90%) respectively were recorded with 120 kg ONP/fad.

Twenty one wheat hybrids and their seven parental genotypes were evaluated in the research farm of the Faculty of Agriculture, Ain shams University, Shoubra El-khema, Cairo, Egypt, in 2016/2017 growing season. The genetic analysis was conducted using Griffing (1956), Method 2, model 1). Significant differences among parent genotypes and their 21 crosses for all the studied traits (days to 50% heading, days to maturity, flag leaf area, plant height, number of spikes/ plant, spike length, number of spikelets/ spike, number of kernels/ spike, 1000-kernel weight and grain yield/ plant) were detected. This indicated that, variability exists among these populations may increase the chance appearance of good new combination that can be isolated in the succeeding generations. Parents versus crosses mean squares as an indication for average heterosis over all crosses were significant for all studied traits. Mean squares of general (GCA) and specific (SCA) combining abilities were significant for all studied traits except spike length trait for SCA which was insignificant. GCA/SCA ratios were more than unity for all studied traits, which indicating that the additive type of gene action is of great importance in the inheritance of these traits. Heterosis over the better parents showed that, the best hybrids were Gemmiza 9xGiza 168, Sakha 93x Giza, 168, Sakha 94x Jawahir-14, Sakha 94x Bob white, Giza 168xAcsad 925 and Jawahir-14x Bob white for grain yield/ plant trait and some of the other studied traits. The best general combiner parents were Sakha 94, Jawahir-14 and Bob white for grain yield/ plant trait and some of the other studied traits. The best SCA hybrids were Gemmiza 9x Sakha 93, Gemmiza 9x Giza 168, Sakha 93x Jawahir-14, Sakha 94xJawahir-14, Sakha 94x Acsad 925, Sakha 94xBob white, Giza 168x Jawahir-14, Giza 168x Acsad 925, Jawahir-14x Bob white and Acsad 925x Bob white for grain yield/ plant trait and some of the other studied traits. These result could be used in wheat breeding programs.

This study aimed to investigate the effect of different concentrations of different water salinity (36, 17, 8, 4, 2 ppt. and salinity level is less than 1ppt.) on growth performance and survival rate (%) of sea bass fry Dicentrarchus labrax. One thousand and two hundred sea bass fry were randomized stocked at twelve indoor tanks; 4 m3 each (two replicate/treatment), with an average initial body weight of (2 ± 0.30 g/fish) at the rate of 100 fish / tank. Fish in each tank were hand-fed with commercial diet (40 % crude protein and 485.582 Kcal GE/ 100 g diet). Fish were fed daily at a rate of 15, 10, 5, 4 and 3% of the body weight daily for the (1:2.2); (2.2:3.84); (3.84:9.2); (9.20:12.70) and (12.70) g/fish : until the end of the experiment, respectively. The daily allowances were divided into three meals at 8.00 am; 11.00 am and 2.00 pm. Fish were fed six days a week throughout the experimental period (167 days). The daily amount of feed was re-adjusted every two weeks according to the actual fish biomass in the tanks. The highest significant values of growth performance parameters were observed when sea bass fry were reared at salinities 8 and 36 ppt. Weight gain of the other treatments were negatively affected (p <0.05) by water salinity. The lowest growth performance parameter was observed by salinity level less than 1 ppt. The highest FCR (1.64) recorded at 8 ppt. compared with (1.73) at 36 ppt. and worsens (1.91) at salinity level of less than 1ppt. The same trend was observed for protein efficiency ratio and condition factor where sea bass fry D. labrax reared at water salinity 8 ppt. recorded the highest value (1.45 and 1.16), respectively, while treatment 6 (less than 1 ppt. salinity) showed the lowest significant (P<0.05) values (1.31 and 1.01), respectively. No mortality was recorded during the experimental period in all treatments. The economic returns studies showed that the total return and net profit were linked to the prices of the raw materials used in the experiment as well as the marketing prices of the fish produced. Total return and net profit showed that the fish reared at 8 ppt. achieved the highest economic return followed by the 36 ppt. and 17 ppt., while treatment 6 (less than 1 ppt.) showed the lowest economic return followed by 4 ppt. Since the feeding cost of these two treatments is 16% higher than the other treatments, which affected the economic returns. However, when evaluating the situation as a high value fish species (like sea bass) with economic value reared in fresh water, this yield is very favorable in terms of cost compared to the selling price.

This study was carried out in two successive seasons (2014-2015 and 2015-2016) at SEKEM company Farm (Bilbase, Sharkya Governorate) on chia (Salvia hispanica) plant which is a new crop introduced lately to Egyptian cultivation as a medicinal plant. The effect of three irrigation levels of different reference evapotranspiration (80, 100 and 120 % ETo) with foliar application of three levels of proline (100, 200 and 300 ppm), salicylic acid (200, 400 and 600 ppm) and putrescine (10, 15 and 20 ppm) in addition to the control treatment (tap water) was investigated on growth and yield of Salvia hispanica cultivated in sandy loam soil with drip irrigation system. The results of the two years experiments indicated that the highest values of plant growth parameters and seeds yield of S. hispanica were obtained from 100 % ETo. While 120 % ETo resulted in the maximum value of roots fresh and dry weights. Foliar-spray application of proline (100 ppm.), salicylic acid (200 ppm) and putrescine (10 ppm) resulted in optimum fresh and dry weights of herbage and roots. Seed yield was higher in plants sprayed with proline (100 ppm) and putrescine (10 ppm), although the differences between them and salicylic acid (200 and 400 ppm) or putrescine (15 ppm) were insignificant in both seasons. This leads us to recommend irrigation of S. hispanica accordingly with 100 % ETo coupled with foliar-spray application of salicylic acid (200 ppm) from the economic point of view.

One day old wheat grain sprouts were used to study the effect of using saline water for sprouting on sprout characters, and changes of some chemical compounds after 2 years wheat grain storage of Gemmeiza 11 cultivar. Sprout characters showed no significant different in storage grain sprouts weight at all NaCl concentration while increased in fresh grains sprouts with increasing NaCl concentration. Sprouts chemical components as affected by storage revealed that storage Gemmiza II had the highest crude protein and the lowest carbohydrate content compared with dry fresh seeds. Non storage grains also had higher protein and lowest carbohydrate and energy content compare with dry fresh grains. The results of phytochemical analysis showed that wheat fresh grain sprouts increase phytochemical compounds and recorded the higher values when using saline water (37 compounds) followed by using tap water (33 compounds) compared with dry fresh grains (30 compounds). Saline water also enhanced the number of phytochemical compounds in two year storage grain sprouts (31 compounds vs. 28 compounds for tap water). Moreover, storage grains decreased the number of identified compounds during sprouting. It can be recommended that wheat grain sprouting is a procedure that has been developed to significantly increase the bioavailability of phytonutrients and phytochemical to ensure the nutritional security of population for Egypt.
